Sharing experiences

01 November, 2013

BMS, BEMS, control, energy management, Schneider Electric

Over the past decade there has been growing interest in the ‘intelligent’ buildings market. Such buildings have been billed as the answer to mounting energy consumption and the accompanying costs — intuitive, automated systems which help managers gain control over how a building is functioning. In reality, intelligent buildings are only now becoming true to their namesake, having delivered little actionable data in the past. Steve Harris of Schneider Electric’s buildings division, examines why.

Warwick University is retro-fitting wireless systems to provide micro-management of the heating system in its social-sciences building. The system hands over control to the building-management team and the building’s occupants, who will individually be able to use their smart phones and tablet computers to control heating on a room-by-room basis.
